The squad responds to a call at an industrial building. They are told that there's a gas leak and everyone could have inhaled it so they bring everyone to Chicago Med. Casey, Kelly, Otis, Mills, Hermann, and Brett go in with them. That's when a guy stands up and says that a new outbreak is coming worse than Ebola that's when he pulls the pin out of a grenade, Kelly pushes him aside but is in the blast. The doctors try to help Kelly among them the brother of Chicago PD cop Halstead, who just started. When Casey tells Boden what the guy said, he tries to keep everyone who was inside there. A doctor tries to find out if the guy is bluffing. Halstead arrives and tries to find out too.
